IMPROVEMENT IN SPRING HINGES.

The Schedule referred to in these Letters Patent and making part of the same.

Tour-ll whom it may concern:

Be it known that I, WILLIAM WELLS, of Cleveland, in the county ofv Ouyahoga and State of Ohio, have invented a new and useful improved Spring -Hinge; and I do hereby declare the following to be a full, clear, and exact description thereof, snflicient to enable those skilled in the art to which my invention appertains to fully understand and to make and use the same, reference being had to the accoinpanying drawing forming part of this specification, and in which 7 Figure 1 is aside view of a double hinge constructed according to my invention Figure 2 is a transverse section thereof, taken in the line .2: 2:, fig. 1; and Figure 3 is a front viewof an open single hinge, constructed on the same principle as that shown ii figs. l and 2. v v

Similar letters of reference indicate like parts in the several figures. I

My invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described and claimed, wherebya much improved and very' superior hinge is produced.

Referring to the drawing A, figs. l and 2, represents the central portion or leaf; and

I 15 B, the side leaves of a-donble hinge.

The peculiarity in the construction of th se leaves A B 13 consists in casting each leaf with a tubular portion or eye near each end, as clearly shown in fig. 1, whereby an open space is left between said eyes.

a a represent the eyes of the central portion A; and

b 1), those cast with the leaves B B.

c c are shoulders cast on the leaves to form stops.

The adjacent edges of the leaves are rounded or beveled to fit closely to the eyes and-to make'room for the springs, and are recessed at i -i for the accommodation of the regulating collars.

. C 0 represent spiral springs, which occupy. the spaces between the eyes a I) and l) a," one end, (I d, of each spring bearingon one of the leaves B B, while the other ends are titted into recesses-in the under side of tension -regulators.

D 1)"represent these regulators, which consist of annular blocks or collars, provided with radial openings, e e, and a recess in the under side for the reception of the end 1" of the spring, as just described.

E E are the pintlcs which pass through the eyes of the leaves, and also through the regulating-collars and the springs, and are provided at one or both ends with screw-nuts, hit, so that the pintles are made detachable.

To regulate the .tensionof the springs, the collars D D are turned-by means of a rod inserted in one of the holes e, or by any other suitable means, until the may be kept in a cavity tbrmed in one of the screw ends of the pintles.

In applying my hinge, one of theleaves, with one spring and regulator, and the central portion A attachcd,issecured to the frame. and the other leaf is screwed to the door. Now, bringing'the parts together,the other spring and regulator are placed in position, and the remaining pintle inserted, after which the tension of the springs is regulated, as de sired, The eyes of the letrcs B B of the single hinge, fig. 3, alternate as in the double hinge. The pintle, spring,

' and regulator are the same, the pin inserted in the latter bearing against one leaf, B, while the end f of the spring rests 'on the other leaf.

By thus arranging the spring andregulator around the pintle between the eyes of the hinge, I dispense with all difiicult and unsightly castings, and produce a hinge'on which the tension can be regulated with certainty and facility, the hinge at the same time presenting a correct and syn'nnetrical appearance.

Another advantageresulting from this construction and arrangement is the increased strength of the leaves, being hung on the pintles by eyes located at or near the ends. Also, by the central arrangement of the spring its strength is exerted on the leaves-at or near the most effectual point.

I do not claim the provision of the pintle with screw-caps or ends; neither do I claim the spring and regulator as new in themselves; but

Having thus described my invention, -What I claim as new, and desire to secure by Letters Patent, is-

The combination, in a single or double spring .hinge, of the uninclosed spring 0, loose adjustable regulating-collar D, pintle E h, and the leaves, all' constructed and arranged substantially as herein described.
